In 4,250 BBY, during the Vultar Cataclysm, Dark Jedi traveled to the Vultar system following a Jedi civil war on Coruscant. In time the dark-siders found ancient technology that suggested that the entire system was artificially constructed by the Celestials. Soon the dark Jedi began using the ancient machines, including the Cosmic Turbine, and ended up destroying themselves and the entire planetary system.
